The confidence intervalsfor [mi=0] and [mi=1] do not overlap with the interval for [mi=2],
and none of them include0. Therefore, it appears thatthe hazard for patients with one or no
prior mi’sis distinguishable from the hazard for patients with two prior mi’s, which in turn is
distinguishable fromthe hazard for patients with three prior mi’s.
Similar relationships holdfor the levels of is and hs, where increasing the number of prior
incidents increases the hazard of death.

Patternvalues
The pattern values table lists thevalues that define each predictor pattern. In addition to the
predictorsin the model, the start and end timesfor the survival interval are displayed. For analyses
run from the dialogs, the start and end times will always be 0 and unbounded, respectively;
through syntax you can specify piecewise constant predictor paths.
The reference pattern is set at the reference category for each factor and the mean value of
each covariate (there are no covariates in thismodel). For this dataset, the combination of
factors shown for the reference model cannot occur, so we will ignore the log-minus-log plot
for the reference pattern.
Patterns 1.1 through 1.4 differonly on the value of History of myocardial infarction.A
separatepattern (and separate line in the requested plot) is created for each value of History of
myocardialinfarction while the other variables are hel d constant.
